yaw if MM Patented Get. 25, 1932 rrEo STATES PATENT OFFICE KENNETH IvI.WILKINS, OF WAUKEGAN, ILLINOIS, ASSIGNOR TO SUPERIOR TBOLLEY SLIDE &EQUIPLIENT COMPANY, OF WAUKEGAN, ILLINOIS, A CORPORATION OF ILLINOISTROLLEY SLIDE WITH LOOKING MEANS Application filed January v 7, 1932.Serial No. 585,249.

My invention relates generally to current collecting devices andparticularly concerns a device which ispreferably secured adjacent theend of a trolley pole to collect or obtain current from a trolley wireby a sliding contact.

In current collecting devices of this character the carrier member isgenerally pivotally connected to a support which in turn is attached toa trolley pole, and said carrier is generally provided with a removableinsert or shoe member which is adapted to slidably engage the trolleywire; and one of the principal objects of my invention is to provide anovel arrangement whereby the insert member provides means for lockingagainst displacement the means which provides the pivotal connectionbetween the support and the carrier member.

Another important object of my invention is to construct a device whichis provided with means for locking the insert member againstdisplacement with respect to the carrier member.

A further object of my invention is to design and construct a devicewhich is comprised of few parts which may be easily and quicklyassembled or disassembled and which may be economically manufactured;and it is also an object to provide a device which forms a compact anddurable unit.

Many other objects and advantages of my invention will appearhereinafter in the description when considered in view of the drawingannexed hereto.

With reference to the drawing which discloses one embodiment to which myinvention is susceptible V j Fig. 1 is a side view of the device inelevation;

Fig. 2 is a section taken substantially on line 22 of Fig. 1; w

Fig.3 is a section taken through a portion of the carrier; and

Fig. 4 is a view showing the means which are employed for pivotallyconnecting the carrier member to the support.

Considering the principles of construction underlying the particularcurrent collecting device shown, numeral 1 indicates a body arepreferably integral with the support.

The side walls or arms 3 as clearly shown are designed to includebearing portions H through which the means extend forpivotallyconnecting the carrier member to the support. The side walls orarms 3 are made rigid by means of an integral rib portion 5 whichextends between the walls. The bearing portions 4 are each provided withan aperture 6 so as to receive a shouldered bushing 7 and said bushingsare preferably arranged in the manner shown.

The carrier member generally designated 8 is provided with a base orbody portion 9. An aperture 10, transversely arranged, is provided inthe body portion of the carrier, and the means which provides a pivotalconnection between the carrier and support consists of a pivot 11 whichextends through the bearings 4 and aperture 10. The pivot 11 is providedwith an under cut slot 12, and an under cut groove 13 corresponding tothe shape of the under out slot 12, is provided in the body portion 9 ofthe carrier member,

and a removable insert member 1 1 is ar-' ranged in the groove 13 andextends through the under cut slot 12 in the pivot 1l and thereby locksthe pivot against displacement. It will thus be evident that a novelarrange ment of means are employed which provide means for locking thepivotal connection against displacement.

As clearly shown in Fig. 2, the upper part of the carrier membergenerally designated 8 is formed with upstanding spaced side portions 15having concave faces or checks 15', and the removable insert 14 isprovided with with a concave groove 16 which conforms more or less tothe curvature of the cheek portions, all of which provides means forreceiving a trolley wire or other conductor. An aperture 17 is providedadjacent each end of the body portion of the carrier member 8 and asclearly shown, the center of the aperture is arranged or located at apoint below the base 18 of the longitudinal under cut groove 13. Anaperture is provided adjacent each end of the insert member 14 at thebottom thereof and as clearly shown, the bolts 19 are adapted to extendthrough said apertures 17 and 20 and when tightened, will provide meansfor firmly engaging or otherwise securing the insert member againstdisplacement with respect to the carrier. A central lon 'tudinal grooveor slot such as 21'is form in the body portion 9 of the carrier memberand obviously facilitates drawing the cheek or side portions 15 of thecarrier member towards each other. It will be noted that each end of thecarrier member is rounded as at 22, and the removable insert is alsorounded as indicated at 23, the provision of which is obvious. Anelement such as 2&24 provides an electrical connection between ghecarrier member and the support there- It will be evident from theforgoing descriptionthat I have designed and construct- Sibed a devicewhich consists of a carrier member and that improved means are providedfor pivotally connecting the carrier member with a support and that aremovable insert member is associated with the carrier mem- 'ber and.provides means for locking the means oviding the pivotal connectionagainst isplacement, and it is apparent that means are provided forlocking the insert member in position with respect to the carriermember. It will also be evident that the device may be easily andquickly assembled or disassembled, and the several parts are arranged ina compact and durable unit so that an eflicient electrical contactbetween the parts is provided.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departi fromthe spirit of my invention; hence do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described or uses mentioned.
